To all whom it may concern:

'Be it known-that I, JAMEsIS. Damn, it citizen of the United States,-residing at South Vienna, in the county of .Clark and 5 State of Ohio,have invented certain new and useful Improvements in Scissors, ofwhichthefollowing is'a specification, reference being had therein to theaccompanying drawing.

object of the invention is to provide an ad justable stop to limit themovement of the cutting blades and enable the amount of this movementto'be regulated to maintain the cutting edges and points in properrelation one to the other. 7

It is a further object of the invention to provide such a stop whichwillbe concealed from view and will have no. projecting parts.

' L In the accompanying drawings, Figure is a side elevation of a pairof scissors em-' bodyingmy inventionfFig. 2'is, a side elevation of theinner side of one of the blades;

and 'Fig. 3.is a: similar view of the inner side of the other blade. 7

In these drawingsI haveillustrated one embodiment of my invention andhave shown the same as applied to a pair of scissors such as arecommonly used by bar-' bers, but it will be apparent that the inventioncan be applied to scissors or shears of various types. The scissors hereshown are of the usual construction comprising the two intersectingblades 1 and 2 pivotally connected one to the other by a pivot screw 3.It will be noted that the inner faces of the blade members 1 and 2 arefiat throughout their length and have no shoulders or 40 projectingstopsof any kind. The shanks of the blade members are slightly offset tobring the finger rings, indicated at 4 and 5, into substantially thesame plane, but these rings-never come into engagement one with limitthe movement of the intersecting blades about their'pivotal centers Ihave provided One of the blades with a recess, one end of which forms astop and have provided the 59 other blade with a part adapted to enterthe recess in the first blade and engage the stop to limit the relativemovement of the blades. In the present instance I have shown the blade 2as provided with a recess 6 tour and extends about the pivotal center ofthe blade. This recess has one end wall straight to form a shoulder,and, if desired, a wear plate, such as indicated at 7 may be mounted inthat end of'the recess. The part carried by the other blade liadapted toenter the recess 6 in the blaile 2, preferably consists of a ball 8mounted in a recess 9 in the inner surface of the blade 1 and of adiameter approximately twice the depth of the recess 9. The recess 9 ispreferably elongated to allow the ball to have movement therein and-anadjustable stop is provided to limit the movement of the ball in onedirection. This stop is here shown as comprising a screw 10 mounted inthe edge of the blade 1 and having its inner end extending into therecess 9. By adjusting this screw the amount of movement permitted tothe ball 8 is limited, and, consequently, the amount of movementpermitted to the blades before the ball comes in contact with the fixedstop of the recess 6 maybe regulated.

It will be noted that I have provided the .throughout their length asthe edges thereof gradually wear away from repeated sharpenings; andfurtherI have eliminated the projecting parts or shoulders common toscissors and shears and often very objectionable, particularly in thecase of barbers scissors. It will be further noted that the constructionis an exceedingly simple one,

.requiring a minimum number of parts and having these parts of such acharacter that they can be provided very cheaply and will be subjectedto little or no wear; and further, having the. parts ofsuch a characterthat the adjustment is. positive and very strong and not likely tobecome broken or disarranged. It will. also be noted that the fingerrings 4 and 5 are connected with the shanks of the blades at points offtheir centers and near the inner edges thereof. This arrangement,particularly in the case of the ring 5, enables the finger which isinserted in the'ring to be supported in substantially the same planewith the other fingers, which rest upon the shank and upon the rearwardlrojecting lip, thus providing a finger su p iort which does not distortthe fingers or tire the same.

While I have herein shown and described one form of my invention it willbe understood that this form is chosen for the purpose of illustrationonly and that I do not Wish to be limited to the details of constructionshown anddescribed, for obvious modifications will occur to a personskilled in the art.

Having thus fully described my invention, what I claim as new and desireto secure by Letters Patent, is

1. Scissors comprising a pair of intersecting blades pivotally connectedone to 'the other, one of said blades having a recess in that sidethereof adjacentto the other of said blades, a ball movably mounted insaid recess, and an adjustable stop carried by the other blade tocoiiperate with said ball to limit the movement of said blades aboutsaid pivotal connection.

2. Scissors comprising a pair of intersecting blades, a pivotalconnection between said blades, one of said blades having an elongatedrecess therein and having a part forming a stop, the other of saidblades also having an elongated recess in the inner surface thereof, aball mounted in the recess in said second blade adapted to project intothe recess in the first-mentioned blade, and adjustable means forlimiting the movement of said ball.

3. Scissors comprising a pair of intersecting blades, a pivotalconnection between said blades, one of said blades having an elongatedrecess therein and having a part forining a stop, the other of saidblades also having an elongated recess in the inner surface thereof, aball mounted in the recess in said second blade adapted to project intothe recess in the first-mentioned blade, and a set screw mounted in theedge of said second blade and extending into the recess therein.

4. Scissors comprising a pair of intersecting blades, a pivot pinconnecting said blades one to the other, one of said blades having asubstantially semicircular groove arranged about said pivot in andhaving one end thereof shaped to orm a stop, the other of said bladeshaving an elongated recess superadjacent to the first-mentioned recess,a ball mounted in the recess in said second blade and projecting intothe recess in the first blade, and a set screw extending into the recessin said second blade to limit the movement of said ball therein.

In testimony whereof, I aflix my signature in presence of two Witnesses.
